Rhizome
The rhizome is the Tige underground, generally horizontal, some Plante S long-lived. It differs from a root by its internal structure, and in what it carries of the Feuille S reduced to scales, nodes and buds, which produce air stems and adventitious roots. It is often a storing body of reserve of the Amidon or the Inuline.
The rhizome can in certain cases ramify considerably and thus allow the vegetative Multiplication plant, which can become proliferating or tracing; it is the case of the Chiendent or the Bambou S.
Certain thickened rhizomes are edible, for example the Gingembre or the Galanga. They are transformed sometimes into Tubercule S: the Potato, the Jerusalem artichoke, the Yam.
The word comes from the Greek ῥίζωμα which wants to say “tuft of roots”, of ῥίζα, the root.
